A model experiment: competitive sorption of Cd, Cu, Pb and Zn by three different soils

Soil and Water Research, 2014
The aim of this study was to evaluate and compare the competitive and individual sorption of Cd, Cu, Pb and Zn on three natural soils: a Gleyic Fluvisol (content of Cd 30, Cu 25, Pb 2297 and Zn 3718 mg/kg), a Gleyic Cambisol (content of Cd 5, Cu 29, Pb ...

Silicon application increases phosphorus uptake by rice: Dynamic rhizosphere processes

Earth Critical Zone
Rice, feeding over half the global population, faces yield constraints from limited soil phosphorus (P) availability, while silicon (Si) can increase P bioavailability by competing for adsorption sites and stimulating rhizosphere phosphatase activity ...

Translocation and dissipation of seven indicator polychlorinated biphenyls from contrast soils cultivated with different root vegetables

Environmental Sciences Europe
The behavior of 7 polychlorinated biphenyls (PCBs) in agricultural Chernozem and Fluvisol soils from the Czech Republic planted with radishes, onions, and carrots was studied. Only the total biomass yield of carrots was significantly reduced (P
